Tabula Rogeriana
The (, lit. "The Excursion of One Eager to Penetrate the Distant Horizons"), commonly known in the West as the (lit. "''The Book of Roger''" in Latin), is an atlas commissioned by the Norman King Roger II in 1138 and completed by the Arab geographer Muhammad al-Idrisi in 1154. The atlas compiles 70 maps of the known world with associated descriptions and commentary of each specific location by Al-Idrisi.Houben, 2002, pp. 102–104.Ahmad, 1992, pp. 156–161. Creation of the Atlas Around 1138, the Norman King of Sicily, Roger II, invited Al-Idrisi, a Muslim geographer, to his court in Palermo, in search of help pursuing his political agenda. Sicily's vibrant multicultural environment led al-Idrisi to accept King Roger's invitation to his court. During the meeting, Al-Idrisi briefed Roger II on his familiarity and personal experiences traveling around North Africa and Western Europe, which prompted Roger II to commission an atlas from Al-Idrisi. To produce the work, Al-I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muhammad Al-Idrisi
Abu Abdullah Muhammad al-Idrisi al-Qurtubi al-Hasani as-Sabti, or simply al-Idrisi (; ; 1100–1165), was an Arab Muslim geographer and cartographer who served in the court of King Roger II at Palermo, Sicily. Muhammad al-Idrisi was born in Ceuta, then belonging to the Almoravid dynasty. He created the , one of the most advanced medieval world maps. Early life Al-Idrisi hailed from the Hammudid dynasty of North Africa and Al-Andalus, which was descended from Muhammad through the powerful Idrisid dynasty. Al-Idrisi was believed to be born the city of Ceuta in 1100, at the time controlled by the Almoravids, where his great-grandfather had been forced to settle after the fall of Hammudid Málaga to the Zirids of Granada. He spent much of his early life travelling through North Africa and Al-Andalus (Muslim Spain and Portugal of the times) and seems to have acquired detailed information on both regions. He visited Anatolia when he was barely 16. He studied in the universit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longitude
Longitude (, ) is a geographic coordinate that specifies the east- west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are imaginary semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, south-east London on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Science
The history of science covers the development of science from ancient history, ancient times to the present. It encompasses all three major branches of science: natural science, natural, social science, social, and formal science, formal. Protoscience, Science in the ancient world, early sciences, and natural philosophies such as alchemy and astrology that existed during the Bronze Age, Iron Age, classical antiquity and the Middle Ages, declined during the early modern period after the establishment of formal disciplines of science in the Age of Enlightenment. The earliest roots of scientific thinking and practice can be traced to Ancient Egypt and Mesopotamia during the 3rd and 2nd millennia BCE. These civilizations' contributions to mathematics, astronomy, and medicine influenced later Greek natural philosophy of Science in classical antiquity, classical antiquity, wherein formal attempts were made to provide explanations of events in the Universe, physical world based on n ...

Bodleian Library
The Bodleian Library () is the main research library of the University of Oxford. Founded in 1602 by Sir Thomas Bodley, it is one of the oldest libraries in Europe. With over 13 million printed items, it is the second-largest library in Britain after the British Library. Under the Legal Deposit Libraries Act 2003, it is one of six legal deposit libraries for works published in the United Kingdom, and under Irish law it is entitled to request a copy of each book published in the Republic of Ireland. Known to Oxford scholars as "Bodley" or "the Bod", it operates principally as a reference library and, in general, documents may not be removed from the reading rooms. In 2000, a number of libraries within the University of Oxford were brought together for administrative purposes under the aegis of what was initially known as Oxford University Library Services (OULS), and since 2010 as the Bodleian Libraries, of which the Bodleian Library is the largest component.

Gabriel Sionita
Gabriel Sionita ( Syriac: Jibrā'īl aṣ-Ṣahyūnī; 1577 at Ehden in Lebanon – 1648 in Paris) was a learned Maronite priest, famous for his role in the publication of the 1645 Paris Polyglot of the Bible. Life Gabriel Sionita was born Jibrayil al-Sahyuni Al Karami in Mount Lebanon, in the Maronite village of Ehden, to an old family of village notables and clerics, known today as the Karam family. Maronite Patriarch al-Rizzi or Sergius Risius (1581-1597) sent Sionita and nine other Maronite children to Rome at the age of seven to study in the new Maronite College. In Rome, he learnt Latin and Arabic on top of his native Syriac, and acquired a slight knowledge of Hebrew. He studied theology, but only went into the priesthood later, in Paris, aged 45. Savary de Breves was French ambassador to Turkey and was interested in Oriental studies. When recalled from Rome, he took two Maronites with him to Paris, to assist in the publication of the polyglot under the auspices of de Tho ...

Matthew Bonnellus
Matthew Bonnellus ( or ; 1130 – 1161) was a rich knight of an ancient and influential Norman family who became the lord of Caccamo in Sicily. He is most famous as the leader of three consecutive revolts against the '' ammiratus ammiratorum'' Maio of Bari and King William I of Sicily. When young he was attached to Maio, who destined him to be his son-in-law, and sent him on a diplomatic mission to Calabria. While there, Bonnellus became romantically involved with Clementia, Countess of Catanzaro, the heiress of Count Robert of Catanzaro. In return for her hand in marriage, he was induced to join the brewing conspiracy bent on Maio's assassination. According to Hugo Falcandus, on 10 November 1160, rumours began circulating in Palermo that "the King was coming that night, at Maio's instigation, to the Archbishop's palace, and that there, in that very street, he was to be slain." It was not, however the king, but the admiral, who was to be slain: with the complicity of the Archbis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravity
In physics, gravity (), also known as gravitation or a gravitational interaction, is a fundamental interaction, a mutual attraction between all massive particles. On Earth, gravity takes a slightly different meaning: the observed force between objects and the Earth. This force is dominated by the combined gravitational interactions of particles but also includes effect of the Earth's rotation. Gravity gives weight to physical objects and is essential to understanding the mechanisms responsible for surface water waves and lunar tides. Gravity also has many important biological functions, helping to guide the growth of plants through the process of gravitropism and influencing the circulation of fluids in multicellular organisms. The gravitational attraction between primordial hydrogen and clumps of dark matter in the early universe caused the hydrogen gas to coalesce, eventually condensing and fusing to form stars. At larger scales this results in galaxies and clust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South-up Map Orientation
South-up map orientation is the orientation of a map with south up, at the top of the map, amounting to a 180-degree rotation of the map from the standard convention of north-up. Maps in this orientation are sometimes called upside-down maps or reversed maps. Psychological significance Research suggests that north-south positions on maps have psychological consequences. In general, north is associated with richer people, more expensive real estate, and higher altitude, while south is associated with poorer people, cheaper prices, and lower altitude (the "north-south bias"). When participants were presented with south-up oriented maps, this north-south bias disappeared. Researchers posit that the observed association between map-position and goodness/badness (north=good; south=bad) is caused by the combination of * the convention of consistently placing north at the top of maps, and * a much more general association between vertical position and goodness/badness (up=good, do ...

Clime
The climes (singular ''clime''; also ''clima'', plural ''climata'', from Greek κλίμα ''klima'', plural κλίματα ''klimata'', meaning "inclination" or "slope") in classical Greco-Roman geography and astronomy were the divisions of the inhabited portion of the spherical Earth by geographic latitude. Starting with Aristotle (''Meteorology'' 2.5,362a32), the Earth was divided into five zones, assuming two ''frigid'' climes (the Arctic and Antarctic) around the poles, an uninhabitable ''torrid'' clime near the equator, and two ''temperate'' climes between the frigid and the torrid ones. Different lists of climata were in use in Hellenistic and Roman time. Claudius Ptolemy was the first ancient scientist known to have devised the so-called system of seven climes (Almagest 2.12) which, due to his authority, became one of the canonical elements of late antique, medieval European and Arab geography. In Medieval Europe, the climes for 15 and 18 hours of longest daylig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabic
Arabic (, , or , ) is a Central Semitic languages, Central Semitic language of the Afroasiatic languages, Afroasiatic language family spoken primarily in the Arab world. The International Organization for Standardization (ISO) assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as ( "the eloquent Arabic") or simply ' (). Arabic is the List of languages by the number of countries in which they are recognized as an official language, third most widespread official language after English and French, one of six official languages of the United Nations, and the Sacred language, liturgical language of Islam.
